What wire decking do I need for 40×48 pallets?
Quick Answer
For standard 40×48 pallets, you need 46" x 42" wire decking with 2500-3000 lbs capacity rating. The most common specification is 4-gauge wire construction with 4" channel depth and 3-4 support bars, priced between $45-75 per deck. This size provides proper pallet support while allowing 2" clearance on each side for safe fork truck operation.
For heavier loads or demanding applications, upgrade to 46" x 46" heavy-duty decking with 3000+ lbs capacity. Always verify your beam spacing (typically 96" centers) and ensure the deck size is 2-4 inches smaller than your beam spacing to prevent binding during installation.

Sizing Calculator Steps
- 1Measure pallet dimensions (length x width)
- 2Determine maximum load weight per pallet position
- 3Measure beam spacing (center to center)
- 4Select appropriate wire gauge based on load
- 5Choose deck size 2-4 inches smaller than beam spacing
- 6Verify capacity rating meets or exceeds load requirements
Beam Spacing Considerations
| Beam Spacing | Deck Length | Load Rating | Notes |
|---|---|---|---|
| 96" centers | 46" | Standard | Most common configuration |
| 108" centers | 52" | Reduced | Wider spacing requires heavier gauge |
| 120" centers | 58" | Heavy duty required | Maximum recommended spacing |
